考场代码：

for(int i = 1;i<=n;i++){
        for(int j = 1;j<=n;j++){
            if(xx[i] == yy[j]){
                printf("%lld ",xx[i]);
            }
            else{
                (tx[i] >ty[j])?printf("%lld ",xx[i]):printf("%lld ",yy[j]);
            }
        }
        puts("");
    }

满分代码：

for(int i = 1;i<=n;i++){
        for(int j = 1;j<=m;j++){
            if(xx[i] == yy[j]){
                printf("%lld ",xx[i]);
            }
            else{
                (tx[i] >ty[j])?printf("%lld ",xx[i]):printf("%lld ",yy[j]);
            }
        }
        puts("");
    }
